 memory is an indispensable unit of a computer and microprocessor based systems which stores permanent or temporary data.

 all of the program and the instructions are stored in the memory. the processor fetches it as and when required.

 register is also a part of memory inside a computer. it stands there to hold a word. a word is a group of 16-bits or 2-bytes.

 a register file is different from a simple register because of capability to hold a modest number of words of information. a word is a group of 16-bits or 2-bytes.

 the very first computer memory consisted of a minute magnetic toroid, which required large, bulky circuit boards stored in large cabinates.

 a minute magnetic toroid is also called as core memory which is made up of a semiconductor. a semiconductor is a device whose electrical

 semiconductor has capability to store data in extremely high densities.

 vlsi (very large scale integration) semiconductor is used in modern computers to short the size of memory.

 vlsi (very large scale integration) is a memory chip which is made up of nmos, cmos, bjt, and bicmos. it can include 10,000 to 100,000 gates per ic.

 cd-rom refers to compact disk-read only memory.
